Picked up this 73 LP Deluxe. It's got P90's, I was told they're SD's. My intention was to swap in a vintage set of mini's that I have laying around because the 2 previous p90 guitars I owned... I just didn't like. But these shocked me, they're staying. By the looks of them, scuffs and corrosion on the poles, they've been in it a while. I don't feel like pulling them to check. I'm getting 7.62 on the neck and 9.2 ohms on the bridge. Any good guesses on what they are would be appreciated.
